120 IBM Enterprise Workload Manager
5.1 Overview of the process
Before building your domain policy you need to carefully assess your environment and plan
your EWLM setup. As with the workload management functions of individual operating
systems, the planning and preparation phase is the most important step to successfully use
workload management capability. You need to collect information from various EWLM domain
resources and decide what needs to be monitored.
The purpose of this chapter is to present an example implementation of EWLM and to give an
explanation of some of the main considerations for designing and building it. The following list
describes our five phase approach to building an EWLM domain. The goal of these steps is to
produce a representation of EWLM domain policy with a measurable business goal that is
easy to understand and that will serve as a basis for future expansion. These steps may not
be a linear process and you may need to move several times between steps three and five.
1. Assessment
a. Defining the EWLM domain
b. Identifying all servers and middleware
c. Identifying all applications
2. Planning
a. Naming the domain policy
b. Defining the user information
c. Defining the directory and port configuration
3. Design
a. Identifying the transactions that request business functions
b. Identifying the processes that request business functions
c. Grouping service classes into a workload
d. Setting service class goals
4. Classifying the work
a. Defining classification filters for each transaction and process class
b. Creating the domain policy at the EWLM Control Center
5. Verification
a. Verifying transaction request classification filters
b. Verifying service class definition
c. Defining and implementing service policy
In addition, we include some information on monitoring and reporting functionality once you
have set up your EWLM domain. This includes reports and monitors which can help you
understand and diagnose performance problems you may have or suspect in your
We provide many tables which you can use to collect information when you organize your
EWLM domain. To collect this information you need to contact various people from your
company. This includes application designers, application developers, operations, system
administrators, and persons who are responsible for particular component monitoring. These
tables may be interim steps or they may be the final definition of your domain policy.
